DESCRIPTIONS OF THE NEW GENERA AND SPECIES. 



Gen. nov. * EUPOLIS. 



CephalothoraXt longer than broad, very broadly truncated at 

 the posterior extremity, the hinder slope, which is rather abrupt, 

 being strongly impressed or roundly excavated. Anterior 

 extremity also broadly and roundly truncated; lateral marginal 

 impressions at the caput distinct but not strong. Height of 

 clypeus less than half that of the facial space and sloping 

 forwards ; profile, nearly level behind the eyes. A slight 

 shallow dip before the hinder slope. 



Eyes, subequal, in two equally but not strongly curved trans- 

 verse rows, of very nearly equal length, the front row slightly 

 shortest. The convexity of the curve of the posterior row is 

 directed backwards, that of the anterior row forwards. The fore- 

 centrals are smallest, but rather large for that position, and are 

 separated by nearly a diameter's interval, a full diameter 

 separating each from the fore-lateral next to it. The hind- 

 centrals are separated by rather less than a diameter from each 

 other, but by rather more from the hind-lateral next to it. The
